Retractable oxygen supply hose mechanism for medical oxygen therapy devices and medical oxygen treatment devices

Abstract

The modification of a spring loaded retractable mechanism currently used for wire to facilitate the quick dispensing and retraction of an oxygen supply hose for medical oxygen therapy and medical oxygen treatment devises. An adaptor is developed to permit the adaptor to be connected to a supply hose reel top surface. The adaptor permits the patient supply hose to be attached to a swivel connector that is fixed to the adaptor cap. The adaptor facilitates the free movement of the adaptor and the supply hose reel to prevent binding or impingement of the patient supply hose.

I claim: 
     
       1. A hose reel mechanism comprising a replaceable spool for medical oxygen supply for treatment or therapy comprising: a spring loaded retractable mechanism having a large reel and a small reel and a retractable spring wherein, said small reel and an axis of said large reel are connected by said retractable spring;   said replaceable spool comprising an upper and a lower discs being attached by a cylinder in between said discs, and an adaptor, at least one tab extending from said lower disc being insertable into at least one groove of said large reel removeably attaching said replaceable spool to said spring loaded retractable mechanism;   a supply hose wound around said cylinder of said spool, an upstream end of said supply hose being connected to a swivel connector in said adaptor via a hole in said cylinder for providing said medical oxygen supply.   
     
     
       2. A hose reel as recited in claim 1 wherein said lower disc includes four winged shaped tabs which are fitted onto four grooves of said large disc. 
     
     
       3. A hose reel as recited in claim 1 wherein said adaptor includes two members threadedly connected to one another. 
     
     
       4. A hose reel as recited in claim 1 wherein said supply hose is attached to a rotatable portion of said swivel connector located a within said adaptor and a fluid source is attached to the other side of said rotatable portion of said swivel connector located externally, whereby said supply hose may be unwound and retracted in an untangled manner.
